FLOOR CONNECTION.

Specification of Letters Patent.

Patented Aug. 11, 1914..

Application filed June 26, 1911. Serial No. 635,419.

nine, a citizen of the United States, residing at Boston, county of Suifolk, State of Massachusetts, have invented a certain new and useful Improvement in Floor Connections, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object a fioor connection intended to be used where it is desired to connect a water closet or other similar fixture to a soil pipe, without the use of plastic packing material such as putty, or white lead.

In most of the floor connections of this kind as heretofore generally constructed there has been a multiplicity of parts and complication of structure which has rendered the floor connection expensive and has tended to impair its efficiency.

My present invention atlords a floor connection which makes a tight joint between the base of the fixture and the upper end of the soil pipe without the use of putty, white lead or the like, and which is simple to construct and of relatively small cost. It is also so constructed that the joint between the pipe and the fixture is constantly wator-sealed and the parts are so constructed that in case of any leakage by the gasket the water will run out onto the floor and not follow down the drain pipe so as to stain the ceiling below.

The invention will be fully understood by reference to the following specification taken in connection with the accompanying drawings, and the novel features thereof are clearly set forth and distinctly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a section of a floor connection embodying my invention. Fig. 2 is a section. taken at right angles to the section of Fig. 1. Fig. 3 is a sectional view of one side of a floor connection embodying my invention as adapted for use in connection with a lead soil pipe.

Referring to the drawings, and particularly to Figs. 1 and 2, at 11 is indicated the upper end of the soil or drain pipe, which in the form shown in these figures is of strong stiff metal such for instance as cast iron or brass. The upper end of the drain pipe is screw threaded as shown 12 to a point a short distance below the upper edge of the pipe and the portion of the pipe 13 from the top edge to the beginning of the screw threads is turned down smooth to receive a gasket 14 made of asbestos, rubber or other suitable material. The floor upon which the fixture rests and through which the drain pipe 11 passes is designated 15, and the fixture itself is designated 16. The fixture is in general of the usual recessed type so that the drain pipe 11 may extend upwardly into the underside of the fixture. On the screw threaded portion 12 is secured an internally screw threaded collar 17 having holes 18 therein to receive bolts 19 on the upper ends of which are located nuts 20. It will be seen that when the nuts 20 are screwed down onto the bolts 19 the fixture 16 is drawn down onto the floor 15, as the collar 17 and drain pipe 11 are immovable. It will also be seen that if the collar 17 is adjusted to the right height the gasket 14 which occupies the space between the underside of the fixture 16, the drain pipe 11 and the upper side of the collar 17 will be compressed and will effectually pack the joint between the fixture and the end of the drain pipe. The collar 17 may be adjusted to the proper vertical position by rotating it on the drain pipe 11 and after the proper level has been attained it may be fixed from rotation by means of a wood screwg21 passing through the collar 17 and into the floor 15. It will be seen that there is a small space left between the top of the gasket 14:, drain pipe and the fixture and that this annular space will hold sufiicient water to make a water seal between the drain pipe and the fixture. As however the interior of the fixture overhangs the edge of the drain pipe and as unless special provision is made the water is not likely to fill this space, I bore a small hole or port 22, see Fig. 2, through the overhanging ledge or shelf so that water may flow directly into the annular groove to form the water seal.

In setting up my joint it is desirable to apply graphite or black lead to the threads of the drain pipe 11 so that no water, in case of leakage, will follow down the threads and so escape to the ceiling of the room below or follow down the drain pipe. If this is done and the joint leaks the water will flow out onto the floor of the room in which the fixture is located. I,

My improved floor connection is put in place in the following manner :-The drain pipe 11 is fixed in place extending up through the floor for the proper distance. Then the collar 17 with the bolts 19, 19, in place in the holes therein is screwed down as nearly as possible to the proper level. The gasket 14 is then put on over the top of the drain pipe 11 and the fixture is set down over the whole. The nuts 20 are then puton and screwed down until the fixture rests upon the floor. The joint is then tested and if it is found to leak the fixture is removed and the collar 17 is raised by giving it one or more turns or fractions of a turn. The fixture is then put in place again and the nutstighteneol. By adjusting the collar 17 to the proper height as thus described, the gasket 14 may be put under suflicient pressure tokeep the joint tightand at the same time the fixture will rest securely on the floor.

In Fig. 3 I have shown my improved fioor connection as constructed when it is to be used with a lead or soft metal drain pipe. Under these circumstances I stiffen the upwardly projecting end of the lead drain pipe 24 by means of a flanged sleeve 25 which is soldered to the lead drain pipe-in the well known manner as shown at 26. This flanged sleeve 25 is secured to the floor by wood screws 27 or the like. It is screw threaded at 28 to receive the collar 17 exactly the same'as is the end of the cast iron pipe shown in Figs. 1 and 2, and forms essentially the end of the drain pipe. Otherwise the construction and mode of operationof the form shown in Fig. 3 is identical with that shown in Figs. 1 and 2.

What I claim is:

1. A floor connection comprising a fixture having arecess at its bottom, a drain pipe extending upwardly into the recess of said fixture, a collar having a water tight joint with said drain pipe, a gasket between the said fixture, the said collar and the upper end of the said drain pipe, and means to draw the fixture down onto the said gasket to compress the same into the space between the fixture, the collar and the upper end of the drain pipe.

2. In a floor connection, the combination with a fixture having a recess at its bottom, or" an upwardly extending drain pipe screw threaded near its upper end, a collar screwthreaded to fit the screw-threaded part of F said pipe and thereby adjustable vertically thereon, a gasket between the said fixture, the said collar and the said drain pipe, and bolts connecting said fixture and said collar and serving to compress the gasket between the fixture, the collar and the upper end of the drain pipe.

3. In a fioor connection, the combination with a fixture recessed at its bottom, of a drain pipe extending upwardly into the recess in said fixture, a gasket making a tight joint between the fixture and the drain pipe, the parts being constructed and arranged to provide an annular space above said gasket and below said fixture, the latter overhang ing the end of the drain pipe and having an aperture smaller than the bore of the drain pipe, and said fixture being provided with a hole to admit water to the said annular space above the gasket.

In testimony whereof I aiiix my signature, in presence of two witnesses.
